ESR Detection of the Isotopic-site-preference in the Jahn–Teller Distorted Benzene Cation Radicals Produced in MCM-41, Silica Gel, and Halocarbons

Isotopic-site-preference was detected in partially-deuterated benzene cation radicals, which were distorted by the Jahn–Teller effect to the D2h symmetry. In all cases, C–H bonds tend to occupy the positions with higher spin densities in the distorted cation.
